We are in our early 50's and have now completed 10 cruises:
QEII Celebrity Summit, Millennium, Infinity, Constellation and Century RCL Explorer and Adventurer of the Seas Golden and Star Princess
I am an American and my husband is Bermudian and we cruise for the enjoyment and we visit ports to get a tiny sample of what the location has to offer. If we like it, we will come back to spend more time at a later date.
